3.5% feeds from an AC source of a PV generating station. The distribu-
tion line is 10 miles long and has a series impedance of 0.01 + j0.09 2 per
mile. The local load is 250 kVA. The balance of power can be injected
into the local utility using a 500 kVA, 3.2 kV Y grounded/13.2 kV delta
transformer T2 with the per unit reactance of 8%. Assume the voltage
base of 13.8 kV on the local power grid side, kVA base of 500, and the
DC bus voltage of 800 V.
Compute the following:
(i) The inverter and the PV generating station ratings.
(ii) The per unit impedance diagram of the microgrid.
